To all whom it may concern.-

Be it known that I, JOHN F. WARNER, a citizen of the United States, resi at Mun cie in the county of Delaware an State of Indians, have invented a new and useful Valiable-Speed Device, of which the following is a specification.

My invention relates to variable'speed devices in which a driving-axle and a driven 1o axle are in axial alinement and so through a counter-shaft and gears that the s eed of the driven axle may be the same as t e driving-axle or the speed may be varied or the direction reversed.

My object is to make a variable-speed device with the driving-axle entering one side thereof and the driven axle projecting out of or accessible on the opposite side thereof, and the said device to have a direct drive and to be compact and light and of the fewest possible gears to get a positive drive and to obtam at least two speeds one way and one reverse, oneof said speeds to be what is known as a dime drive andto have no cars runninginmeshonthedirects ;'a o,toob

min these results by sliding the required gears into mesh, so as to get the desired s positive. and with no slip, or into direct clutch engagement for a direct drive; also, to make 0 the said device very short, preferably by arthe speed-varying or coupling gears and mounting them on counter I o: parallel to the drivingaxle,and to ob tam the s varying from direct speed or 5 direetdnve by sh the coupling earned encounter-aha and to leave the direct-driv ng gear to slide only for direct clutch engagement, at which time the said drivinigear preferably slides out of mesh 40 with t e coupling-i133 I obtain these obects with the m illehsti'lated in the accompany ng 'w 1ngs,1nw 'c Figure 1 1s a longitudinal sectional view of my games, showing the driving and driven 5 axles in axial alinement with the and dr ven gears ands counter-shaft carrying a pair of speed-varying or coupling gears-and means for sliding said coupl ng and driving ghosts 2 is an end view of my device, 5o the relation of the counter-shafts to each 0 er and to the driving-axle, also showmgthe deviceandsupportinglug. .31sasect1onofmydeviceona line A, F|g. 1,showing the relation of the entire 3 Egmwhanism and the shifter,

Figs. 9,10, 11, 12, an .13 show the driven axle made in a variety of forms and in variousshapes and still kee s the driven axle in axial ,alinement with tl ie driving-axle and shows the driven axle adaptable-for a variety 'of driving connections, Fl l2 and 13 show particularly the driven a e and driven gear made of one piece and a driven member carried on the said driven axle.

Similar numbers refer to similar parts throughout the several views.

My device consists of the hollow casing 2,

with the removable cap 1, in which is mounted the driving-axle 23 and driven axle 34 in axial alinement, and parallel to these axles are three separate axles or counter-shafts 35, 31, and 36, arranged to slide longitudinally. These counter-shafts have long bearings 35, 26, and 36 in the hollow case 2 and similar" bearings in the cap 1. I put studs 39, 38, and 40 in the counter-shafts, respectively, and these studs fit into agroove 19 in the controller 18, which is-rotatively mounted on the extension 22 of the case 2 and held in place b the collar 21 and set-screw-20. The

control or is rotated by the rack 15, carried in the support 14, which is secured to'casing 2 by screw 10. The teeth in said rack engage a gear 16, secured to controller 18 by screw 17. The stud 38, projecting from countershaft 31, slides in a slot 25, cut in the extension 26, which is integral with drum-head 27 Countershafts 35 and 36 have similar slots. On the driv in -axle 23 and by the featherkey 13 is shda 1y mounted the drivin -gear 12, which has a clutch extension 5 acing; I and adapted to engage a similar clutch ex-,

tension 4 on the driven gear 3, which engages with and is mounted on the driven axle 34.

device is to be used requires-attimes that the. driven gear be reversed in direction and at other times to revolve in the same direction as the driving-gear but slower. In myivar i able-speed device l use only one ear on the Idriven axle and onlyone gear on t e driving- 5 The purpose for which my variable-Speed axle and these mounted practically side by side, separated only by the clutch extensions 4 and 5, so it requires a couplingear 8 and 9 to transmit the power from the 'ving-gear 12 to the driven gear 3. The coupling-gear consists of two gears made from one piece or of two gears so arranged as to rotate together on the counter-shaft, and the variation of speed between the driving-axle 23 and the driven axle 34 is obtaimxl b making the driving-gear 12 smaller than t e driven gear 3 and the coupling-gears 8 and 9 to match. The couplin -gears are carried b a counter shaft 31 am? so arra ed that w en the controller 18 is rotated t e cam portion 55 will push the counter-shaft 31 and coupling-gears 8 and 9 longitudinally into a position where the gear 9 will engage the driven ar 3, and asthegearSistwieeaswideast edri ar 12 gear 8 remains in engagement wit t e driving-gear l2 and the speed of the driven axle 34 will be slower than the speed of the driving-axle 23, both axles revolving in the same direction. To reverse the direction of the driven axle 34, I slide counter-shaft 36 longidudinally, which carries a single long gear or two gears 6 and 6(preferably made of one piece) into such position that gear 6 will engage the driven gear 3 and gear 6 will engage gear 8,with which it is'inmesh. Then gear 8 acts as an intermediate gear, and I get a reverse motion to the driven axle 34. To get a direct speed, I so rotate the controller 18 that the cam portion 55 will slide the c0untershaft 35i1which has a shfiiteh r dnr lember 37, en-

aging e cove 11 o t e 'ving-gear 12, v v ch mak sf clutches 4 and 5 engage each 0 er. This shifting movement slides the driving-gear 12 out of engagement with the large coupling-gear 8, so the direct drive is through no gears and no gears are running idle in mesh.

The coupling-gears 8 and 9 may be made of one piece of material or they may be built up; but to va the speed of said axles it is necessary to ave one of the said ars larger than the other. The reverse cou ggears 6 and 6 may be made of one or more ieces, or theyhmay be made straight in one o ear, or t e two rs ma va in size, fig to what s I desire Zn this reverse movement. I s ow both here the same size. The counter-shafts may bemade immovable and the coupling-gears made to slide thereon; but I prefer the counter-shafts to slide longitudinal The driving-axle 34 isshownin the hub o the driven gear 3; but the driven gear may be made in one piece with the driven axle, as shown in F' 9, or the driven gear may be made in one s ort axle and gear combined in one piece and carryAor eng a separate driving member, as shown 10, 12, and 13. Fig. 11 shows a universal cou ling carried by the driven gear.

ith my variable-speed device as shown new the driving-shaft enters on one side of the casing and driven member is on the o posite side, so my drive and the variation is tllrough the device as a whole, not in and out on one side, but on opposite sides.

What I claim as new, and desire to secure by Letters Patent, is
